Also fun fact: In actual TF2 Lore, Jay Pinkerton mentions in tweet of 2015 confirms that it just Nine Mercenaries, like RED/BLU Mercs are completely the same person, no clones, no differentiate for the non-game fiction (Shorts, comics, posts) there's only one Scout, one Soldier and etc. No clones. In the comics and not in-game universe because meet the team videos are not actually canon but everything is a mess. They changed their team colored uniforms everyday for more variety of their battles and when the Robot invasion begins, they joined RED that way they'll avoid the confusion of robots.
